Be it known that we, VIIJJA'M E. Bus and l/VILLIAM Srirrsorr, a citizenof the United States of America and a subject of the King of GreatBritain and Ireland, respectively, residing at Detroit in the county oflVayne and Stateof Michigan, have invented certain new and usefulImprovemerits in Trolley Switches, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates'to'trolley switches. an dhas for itsobject theprovision'o'f an improved construction by means of which a trolley maybe readily moved from one track to another in which the pivot secur ingthe angularly adjustable track P01131011 to a stationary track portionhas its axis of rotation in registration with the gap be tweenthe-angularly adjustable track portion and the stationary track portion;in

which a wheeled truck supports the free end of the angularly adjustabletrack portion and is engageable with a keeper for register ing the freeend with the other stationary track portion. Another object of theinvention is to provide a, pivot for the angularly adjustable trackportion. comprising hinges at theupper and lower sides thereof, thelower hinge being flat to permit ofpassage of the trolley, and theupper, hinge having one hinge member bifurcatedand embracing theothertobetter take care of the A further object is the provision ofastop! at the free end of the angularly adjustable track portionextending adj acent to the end of a branchtraek when the angularlyadjustable portion is in registration with the main track to preventaccidental disengagement of a trolley from the branch track. Otherobjects of the invention reside in the "novel features of constructionand combinations and arrangements of parts more fully hereinafter setforth;

In the drawings:

in detail, this frame Work comprises the iendi angle bar 7 extendingtransverselyof and rigidly secured tothe rear traclr'portion 2, andbranch track 4, the end angle bar sextending transversely of andrigidlysecured to the front track portion; 1 andtheside angle bars9rigidly secured tothe ends of the endangle bars 7 andS.

The angularly adjustable portionB hasits front endjregistering with thefront track portion 1 and is slightly spaced therefrom to permit oflimited swinging to register-the rear end of the .angula rly adjustableportion with the f rear track portion '2' and branch track 4. This frontendis pivotally secured to the front track portion with the aX-is of'thepivotin registrationwith' the gap between the 1 angularly adjustableportion and the f front track portion. 'lhispivot comprises the upperandlower hlnges l0 and ll,' and as shown particularly in Figures 7and-85athe' upper hinge 10 has the pair ofcooperating hinge members 12and 13 respectively 53- edly secured theupper flanges of theangularlyadjustable portionfi and track portion '1. For the purpose of providinga, c v simple construotion'ofupper hinge whichis eoinparatively cheaptomanufacture and at l I the same time will properly takefoareof'the istresses, the 1 hinge member. 12 is bifu'rcatedi and com-prises theloweif section 14 and the upper section 1 5, the former of which isformed of agobd weeringinieteriiilsuch as steel, While the latter isformed of a cheaper material such as cast iron. The pin'16 the axis ofWhich i'egis't'ersiwith the gap between the angulerly adjustable'Iportion'3' and front track portion 1, is fixedly secured at its upperend 1n the upper section 1-3, and extends through the hinge member 13einbriiced by the furcations of the hinge member 12 1nd into the sectionlet. Thelo'wer hinge 11 as" shown particularly in Figures 9 end lO isformed of the 'coope'reting'hingemembers and 18 which arerespectivelyfixedly secured to the lower feces of the lower flengesofthe angulerlj" adjustable portion 3 and front track portion 1. v Thesehinge members are flat and furthei'nior'ethe hi1 gemembei 17 'isprovided with the Circular recess T open h its outer side for engagementthe circularjheed 20 of'the hingenieniherj18 theerruiig eni ent" being:such the't but] enipamtirelylittle spe ce is required belo W: the lowerflenges of the angula'l'ly adjustehlei portion and front. port-ion,thereby" redueing the amount of cleiirzi nce in 'the i rziihe of'tlie"eel-- ley 5 neces I thereof.
